Yeah, the game itself is pretty good so far. Though I will say it doesn't seem like much has happened at this point (just started chapter 2). By chapter 2 in the first game, shit had already gone down.
But yeah, just pointing out technical flaws I wasn't expecting. Another one I didn't mention is the voice volume. It could have used some compressing. Sometimes it's super soft and completely overshadowed by the BGM (which I had to turn lower while keeping voices at max), but it's perfectly fine and sometimes even too loud when yelling is going on (and it's Corpse Party, so there's a lot of that). I don't think that was an issue in the other games, but it's been a while so I don't really remember.
Maybe playing on an actual Vita with headphones and not a PSTV would make a difference, but I don't want to do that.
